TRUCK.

Application filed May 5,

To all whom t may concern.'

Be it known that I, CHARLES `W. WEST, a citizen of the United States,residing at Tigard, county of Vashington, State. of Oregon, haveinvented certain new and useful Improvements in Trucks, of which thefollowing is a specification.

NIy invention relates to trucks in general, and particularly to trucksadapted for handling the iron drums that are commercially used for thetransportation of oil and the like. The object o-f my invention is toprovide such a truck as will lift and hold the filled drum securelyraised a short distance from the ground in a position to be easilytransported upon the truck.

I accomplish this object by means of the construction illustrated in theaccompanying drawing, which is a part of this application for LettersPatent, like characters of reference indicating like parts throughoutthe several views thereof, and in which:

Fig. 1 is a side elevation of my truck with a drum held therein inposition for transportation.

Fig. 2 is an end elevationof the same, with the drum shown in dottedlines upon the ground previous to being raised.

Fig. 3 is a plan view of the truck.

Fig. 4 is a sectional plan view upon line 4 4 of Fig. 1.

Fig. 5 is a detail sectional elevation of the lifting cam upon anenlarged scale, and

' showing the band clamp in lowermost posllIl() tion.

Fig. 6 is a view similar to Fig. 5 but lshowing the band clamp inposition for carrying the raised drum.

Fig. 7 is a View similar to Figs. 5 and 6 but showing the band clamp inits uppermost position.

Fig. 8 is a view of the lifting cam from the direction of the arrow 8 ofFig. 7.

Fig. 9 is a fragmentary view of the drum and a section of the clampingband.

In general my truck consists of a truck body having mounted thereupon avertically movable band clamp adapted to engage and hold the drum, meansof elevating the band clamp, and means embodying a novel lifting camadapted to hold the drum in raised position and to lift the band clampabove the drum as the latter stands upon the ground before or afterbeing lifted.

The truck body consists of a pair of upright'membP/ITS .1Q ,beingconveniently ,Steel 1923. serial No. 636,951.

channels as shown in the drawing.A Mounted upon the lower ends of saidmembers 10 are wheels 11. A substantially semicircular yoke 12 issecured upon the lower ends of the members 10 extending rearwardtherefrom, and forming an abutment to contact with the drum asvthe truckis wheeled up thereto, thus positioning the drum within the truck. Acastor wheell?) is mounted upon lll is provided for convenientlytransporting the truck manually, said handle being most convenientlypivoted upon the axles of the wheels 11 and high enough to swing overthe top of the members 10, so that the truck may be either pushed by thehandle extending towards the rear as shown in full lines in Fig. 1 orpulled by the handle extending towards the front as shown in dottedlines in Fig. 1. Hooks 15 are provided to rbrace the handle 14 to theupright members 10.

To grasp the drum 16 for the purpose of raising it I provide a bandclamp 17 operated by a right and left hand threaded screw 18 mountedupon the ends of said band 17 by trunnioned nuts 19 and operatedAmanually by ahand wheel 20, as shownv in Fig. 3. The band 17 isconvenient-ly lined with blocks 21 o-f wood or similar material, and toallow the blocks 21 to. disengage themselves readily from the flange o-fthe drum the upper ends of the blocks-are beveled, as shown in detail inFig. 9.

To raise the band 17 I provide a pair of novel cams 22 mounted above theband 17 upon the members 10 by suitable boxes, and connected by a shaft23. A hand lever 24is mounted upon one of said cams 22 to operate them.A convenient method of mounting said lever is by supplying a squared end25 upon one of said Cams to receive the hub of the lever, and securingthe lever thereupon by a nut threaded upon an extension 26 of the cam,as shown in Fig. 8.

The function of Jche cams 22 is three fold,

Yfirst to lower the band 17 so it may engage the drum, second to raisethe drum and hold it securely in raised position, third to raise theband 17 above the drum when the truck is idle. These three functions areillustrated in detail in Figs. 5, 6 and 7.

e5 said yoke centrally of the truck. A handle f The cams areconstructed-with a substan- I y raised position.

` n The operation of my truck is as follows:

The truck is Wheeled up to the druin until the drumcontactsnvvith theyoke l2 and is thus properly positioned Within the truck fbody toreceive the band 17..A vThe lever 24 is then turned until the cams 22are' in thepposition sho'ivn' in Fig. 5 and the band 17 in itslowerinost position and .embracing the upper end of the drinn. The band17 is then clamped upon thel driin by means of th'e handwvlieel 2O.V Thelever 24 is then turnedv until the cams 22 assu'ine the' position shownin Fig'. 6.`k The drui'n is thu's automatically suspended upoii thetruck, because the Cables 32 have passed beyond the center of the sliaft23 and the Weight of the drum is tending to rotate the eanis 22counter-clo'ckwis`e5 or iiithe direction of the ai"- r'oW of llig. 6,-Wh-ich rotation is rendered impossible by reason of the i'ini27 of thecams contacting ititli the Cables 32, as shown in Fig. v6. Thus a simpleInve'nient of the lever 24 raises the druiii and locli'sV it intrans'portedV upon the ti'iclrto any desired destination. To loivei vthedrum tok rthe ground againthe liever 24 is rotated clockv'v'ise thusreturning the Cams to the position of Fig. and loiveringthe drum,Whereupen the band '171s' released frein the drum The dr'uni may theirVbe by means of the hand Wheel 20". The band 17 is then raised clear ofthe top of the drum 'by rotating,` the lever 24 counter-clock-Wise untilthe earns-assume the position shown in /Fig 7, whereupon the band 17Will have beenV raised to its uppermost position above the top of thedrum, as shown in Fig. 2.

My device may be made of any size, and constructed of any materialsdeemed convenient and suitble for a device of this character, and tvhileI have'illu'strated and described a form oi' Vconstruction andarrangement o'f parts found desirable in inater'ializing my invention, IWish t0 Vinclude in this application all mechanical equivalents andsubstitutes that' may 'fairly be elonsidered to come Within `thes'vco'pe and purviexv' of lIii'y invention as'detiii-e'd in the ap-13`er`ide`dV claim. Y

Having' disclosed my invention so'. that others may be enabled toeo'iistruet andto use the saine, what I claim as new, and de- Sile to'Secure VLetters' 'Patent is:
